Abstract

A seal (100) for sealing a lubricant space prevents lubricant (320) escaping. A rolling stand has a seal of this kind. The seal (100) is made at least partially from elastic material. To enable a pressing force FR, with which the bottom face (112) of the seal is pressed against an opposite contact surface (218), for example of a roll journal (212), to be variably set, the seal (100) has at least two cavities, which are separated from each other in the circumferential direction and which are open towards the lubricant space of the bearing.
